RCV001868599 | SCV002114663 | uncertain significance | Muscular dystrophy-dystroglycanopathy (congenital with brain and eye anomalies), type A14; Muscular dystrophy-dystroglycanopathy (congenital with intellectual disability), type B14; Autosomal recessive limb-girdle muscular dystrophy type 2T | 2022-07-19 | criteria provided, single submitter | clinical testing | In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is expected to disrupt GMPPB protein function. ClinVar contains an entry for this variant (Variation ID: 1313532). This variant has not been reported in the literature in individuals affected with GMPPB-related conditions. The frequency data for this variant in the population databases is considered unreliable, as metrics indicate poor data quality at this position in the gnomAD database. This sequence change replaces proline, which is neutral and non-polar, with serine, which is neutral and polar, at codon 24 of the GMPPB protein (p.Pro24Ser). |
